The hexagonal cloud pattern at Saturn's north pole as seen by the Cassini spacecraft. Each side of the hexagon is about 14,500 km (9,000 miles), larger than the Earth's diameter. The bizarre pattern was first discovered in 1988 by scientists reviewing data from NASA's Voyager flybys of Saturn in 1980 and 1981, but its existence was not confirmed until NASA's Cassini spacecraft observed the ringed planet up-close years later.

Saturn’s North Pole • A sequence of seven images of Saturn's north polar region from NASA's Cassini spacecraft. The images were obtained in November 2012 and have been reprojected to show the north pole from directly above. The sequence has been tweened to make the cloud motions smoother.
